Optical Ground Wire

OPGW can combine overhead grounding and fiber-optic communication functions in transmission networks.

Fiber Optic Overhead Cable

ADSS can be used for aerial fiber-optic communication applications where an all-dielectric self-supporting cable is required.

Grounding Conductors

Ground wires and related conductors can be selected according to the transmission line design.

Typical Applications

• Long-distance transmission lines
• Overhead grid networks
• Transmission towers

How to Select a Transmission Conductor

Important parameters include:

• Required ampacity
• Conductor size
• Voltage level
• Span length
• Sag and tension requirements
• Mechanical loading
• Wind and ice conditions
• Operating temperature
• Corrosion and environmental conditions
• Applicable conductor standard

International Standards

Transmission conductors may be manufactured according to applicable standards such as ASTM, IEC, BS EN, AS/NZS or customer-specific specifications.The applicable standard should be confirmed before quotation and production.

FAQ

• What is the difference between AAC, AAAC and ACSR?

AAC is an all-aluminum conductor, AAAC uses an aluminum alloy conductor, while ACSR combines aluminum strands with a steel core to provide higher mechanical strength.

• Which conductor is suitable for long transmission spans?

The selection depends on required electrical capacity, span length, mechanical loading and project design. ACSR, ACSS and other high-strength conductors may be considered depending on the application.

• Can you supply OPGW for transmission projects?

Yes. OPGW requirements can be evaluated according to fiber count, mechanical requirements, electrical requirements and project specifications.
